Hi
I'm doing some experiments with LMDB trying to emulate a columnar
storage database using roaring bitmaps and other tricks.
The initial results are promising, but I ask myself, is a row based
storage like LMDB appropriate for implementing a columnar database or
are there better, more efficient ways/formats?
What makes you think LMDB is either row- or column-based? It has no concept of
either, that's purely an abstraction created by higher level code.
